Answer:
1017.36 square miles
Step-by-step explanation:
Since the diameter of a circle is twice the radius, the radius of this circle is 36/2=18. Since the area of a circle is 
, the area of this circle is:

Answer:
Subtract 3.
Step-by-step explanation:
x = 7
10-3 = 7
Start at +17 on the y-axis. your slope is 8.
To find the circumference of a circle the formula is pi times diameter. The radius is half the diameter, so you have to find the diameter by multiplying 2.75 by 2. you get 5.5. Pi is around 3.14, so 5.5 times 3.14 is 17.27. Because you have to convert feet to yards, divide 17.27 by 3 (there are 3 feet in a yard). You get around 5.76. Because if Alexa bought only five meters of lace, she will run short, she needs to buy 6 meters of lace.
